# D3D12_STREAM_OUTPUT_BUFFER_VIEW

> Describes a stream output buffer.

Describes a stream output buffer.

## Syntax

```cpp theme={null}
typedef struct D3D12_STREAM_OUTPUT_BUFFER_VIEW
{
    D3D12_GPU_VIRTUAL_ADDRESS BufferLocation;
    UINT64 SizeInBytes;
    D3D12_GPU_VIRTUAL_ADDRESS BufferFilledSizeLocation;
} D3D12_STREAM_OUTPUT_BUFFER_VIEW
```

### Members

*BufferLocation*\
Type: D3D12\_GPU\_VIRTUAL\_ADDRESS

A D3D12\_GPU\_VIRTUAL\_ADDRESS (a UINT64) that points to the stream output buffer.
If **SizeInBytes** is 0, this member isn't used and can be any value.

*SizeInBytes*\
Type: UINT64

The size of the stream output buffer in bytes.

*BufferFilledSizeLocation*\
Type: D3D12\_GPU\_VIRTUAL\_ADDRESS

The location of the value of how much data has been filled into the buffer, as a D3D12\_GPU\_VIRTUAL\_ADDRESS (a UINT64).
This member can't be NULL; a filled size location must be supplied (which the hardware will increment as data is output).
If **SizeInBytes** is 0, this member isn't used and can be any value.
